Fix Share button referral link to use dl.edge.app

The side-menu Share action built its referral URL from the bare website
domain (edge.app), which broke AppsFlyer appreferred attribution
(refDeviceInstallerId). Route the share link through the dl.edge.app
deep-link subdomain so the appreferred parameter is tracked, matching how
other af= attributions already work.

CHANGELOG.md

@@ -5,6 +5,7 @@
 - added: NYM swap provider (`nymswap`)
 - changed: Route maestro test builds to a dedicated Zealot channel so they no longer appear in the production release list.
 - changed: Hide the wallet "Get Raw Keys" option behind Developer Mode, while still showing it for wallets that fail to load.
+- fixed: Share button referral link now uses the dl.edge.app deep-link domain so appreferred attribution is tracked
 - removed: SideShift `privateKey` from env config; the swap integration no longer sends the affiliate secret header.
